None of them. Resource paths are interpreted, not hard coded. It's formed via concatenation of $domain + ":" + $block_registry_name and later is it parsed to locate the actual file. ALL assets are referenced this way.

So I downloaded a Feed The Beast Forge Server (FTB Presents Direwolf20 1.12 Version ID: 2051 to be exact) directly from the official website but I can't open the forge-1.12.2-14.23.5.2855.jar I tried the usual solutions like reinstalling, tried Java 8, which worked for another person, then installed the newest version of Java, but I still can't open the forge.jar https://imgur.com/a/mYfSOTF This shows both my server files and the error code I get when trying to open the forge.jar using cmd.  I hope somebody can help me out. Thanks in advance.
